Beyond Folic Acid: 5 Key Nutrients To Discuss With Your Doctor During Pregnancy

Pregnancy Nutrition: 5 Important Nutrients To Discuss With Your Doctor

Folic acid is widely recognised as an essential nutrient during pregnancy, particularly because of its role in early fetal development and in reducing the risk of neural tube defects. However, pregnancy nutrition extends well beyond folic acid.

With National Nutrition Week highlighting the importance of informed dietary choices, Dr Rajeev Agarwal, Senior Infertility Specialist, Director and Founder of Dame Health, recommends taking a broader approach to prenatal nutrition. Individual nutritional needs can vary depending on diet, health conditions and the stage of pregnancy, making personalised medical advice important.

Here are five nutrients worth discussing with your healthcare provider.

1. Vitamin D

Vitamin D supports healthy bones and works together with calcium during the development of the baby’s bones and teeth.

Deficiency can occur in people who do not get adequate dietary or sunlight exposure. If a deficiency is suspected, a doctor may recommend testing or supplementation. Foods such as fortified products, egg yolks and some fatty fish can contribute to vitamin D intake.

2. Iodine

Iodine is needed for normal thyroid function and plays an important role in fetal brain development. Pregnancy increases nutritional requirements, so ensuring adequate iodine intake becomes particularly important.

Iodised salt, dairy products, eggs and seafood are among the dietary sources of iodine. Supplements may be recommended in certain cases after consultation with a healthcare professional.

3. Choline

Choline is sometimes overlooked when discussing prenatal nutrition, despite its role in fetal brain and spinal cord development.

Eggs are a particularly useful source, while milk, meat, soy products and peanuts can also contribute to daily intake. Since some prenatal supplements contain little or no choline, women may want to discuss their dietary intake with a doctor or registered dietitian.

4. Vitamin B12

Vitamin B12 contributes to normal nervous-system function and red blood cell production. Women who follow vegetarian or vegan diets may need to pay closer attention to their intake, depending on their overall diet.

Meat, fish, poultry and dairy products are common sources of B12. Those who consume few or no animal products should speak with their healthcare provider about whether fortified foods or supplements may be appropriate.

5. Zinc

Zinc supports several essential processes, including cell growth and immune function. Maintaining a varied and balanced diet can help provide adequate amounts during pregnancy.

However, taking additional supplements without medical advice is not recommended. Nutritional requirements differ between individuals, so supplementation should be based on a healthcare professional’s guidance.

Questions To Ask Your Doctor

Women who are pregnant or planning to conceive may consider discussing the following with their doctor:

Does my current diet provide the nutrients I need during pregnancy?
What nutrients are included in my prenatal supplement?
Am I at risk of any nutritional deficiencies based on my diet?
Would I benefit from any blood tests?
Do I need additional supplements, or are there any I should avoid?
Folic Acid Still Matters

While discussions around different forms of folate have become more common, CDC guidance continues to identify folic acid as the only form of folate proven to help prevent neural tube defects.

The presence of common MTHFR gene variants does not, by itself, mean that a person cannot process folic acid or should automatically replace it with another form of folate.

Folic acid therefore remains an important part of prenatal nutrition, but it should be considered alongside other nutritional needs. Vitamin D, iodine, choline, vitamin B12 and zinc can all contribute to a well-rounded pregnancy nutrition plan.

The key message during National Nutrition Week is to avoid relying solely on assumptions or supplement marketing claims. Instead, review your diet and prenatal supplements with your doctor and make nutritional decisions according to your individual needs.
